I. Walk up the main stairs to the third floor of the GG building. At the head of the stairs you will encounter
a large rock that was collected from the Pennington Formation. This particular sample is sandstone - a
common sedimentary rock type. Read through the description to determine when the sediment that
comprises this rock was deposited. The texture that you see on the exposed surface of this rock is the
fossilized burrows of small marine organisms.
01. During what PERIOD of geologic time was the sediment of the Pennington Formation formed?
(Note: Use the geologic time scale found in your textbook or on the class website.)
Mississippian Period
02. What specific term applies to the preserved burrows, tracks and trails of the animals or plants?
Trace Fossils
II. Read the information about the sample of Athens gneiss to the left of the Pennington Formation.
03. What type of rock (sedimentary, igneous or metamorphic) is Athens (biotite) gneiss?
Metamorphic rock
III. Go through the glass doors in front of you and there is a large display case. The case contains examples
of several minerals. Take a look at the mineral samples. The shapes are a function of the crystalline
structure of the minerals. Look around in the case at some of the samples.
04. What is the chemical formula of the minerals hematite, calcite and celestite?
Hematite: Fe2O3 Celestite: SrSO4 Calcite: CaCO3
IV. Turn right and walk down the hall
